Decode ALE Transissions On the Go!

With this app, you can decode Automatic link establishment (ALE) MIL-STD-188-141B transmissions. ALE is the standard for automatically initiating and sustaining shortwave radio communications.

Just set it next to the radio's speaker, tune in an ALE frequency, and watch the decodes. Or for even better reception, use a pair of earbuds, plugged into the radio's headphone jack, rather than the internal speaker.

You can display all decoded packets, or have duplicates ignored, and concatenate data into one message.

You can save decoded ALE packets to a file to view later, or transfer to your computer via iTunes.
